[jira] Commented: (HADOOP-3395) Namenode.initialize() sets the
default filesystem uri to an ip6 address (0:0:0:0:0:0:0:0)
[ https://issues.apache.org/jira/browse/HADOOP-3395?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=12965200#action_12965200 ]
Trygve Sanne Hardersen commented on HADOOP-3395:
------------------------------------------------
I hit this today with 0.20-append on Debian when using 0.0.0.0 as the NameNode IP. Setting java.net.preferIPv4Stack for the Java process seems to solve the problem, as it makes the socket actually use 0.0.0.0 and not the ipv6 version.

> When starting the namenode, I would get the following exception:

> I tracked this down to NameNode.java line 127 and 128. The socetAddress returned by this.server.getListenerAddress() is an ipv6 style address with colons. Then this is set as the default filesystem which causes problems on the next call to FileSystem.get.
> I replacedthe line:
> this.nameNodeAddress = this.server.getListenerAddress();

> this.nameNodeAddress = socAddr;
> And this made it work for me. However, I gather this would break support for ephemeral ports? Is there a better way for me to fix this, maybe disabling ipv6 elsewhere?
